Description

This caliber 1411 of Ronda S.A. was made in the 70ies or 80ies and is a very simple pin lever movement with only one jewel (Ellipse). The balance in beared in two plastic(!) bearing, whose red color shall remind of synthetic jewels. It is easy to understand, that this movement won't last very long and won't be ultimately precise, too.

It is the reduced version (no center second indication) of the base caliber Ronda 1413.
